Stay Secured: An Introduction to VPN
Business nowadays is all about global market and logistics. Companies seek fast, secure and reliable communications. During the growth of the internet, businesses extended their networks. In an earlier time, intranets came into existence.These are sites designed only fоr the uѕе of company employees. Now, companies can now create VPN (Virtual Private Network) to accommodate the demands and needs of remote employees and distant offices.
VPN, also called virtual private network, is a network that is layered on the basis of a computer network and uses a public telecommunication infrastructure like the Internet. Primarily it uses virtual connection routed through the Internet from a company’s private network to the remote site or employee. VPN is provided to individual users and remote offices for them to have secure access to their organization’s network. Furthermore, companies and organizations use VPN to send voice, video and data in a private manner. When data travels over the VPN, it is not visible; rather it is wrapped up in the network traffic. Thе traffic with the VPN appears to bе just another traffic stream.
Thе VPN permits connecting devices to the Internet through broadband connection or normal data subscription, providing an extra layer of security and privacy to all activities carried out by a user online.
VPNs are mostly used by business and employees to connect to intranets when working remotely, but with more people sharing increasingly private data over online services than ever before, everyone might want to consider using a VPN.
How the VPN Works
A virtual private network creates a secure tunnel between electronic devices such as computers or mobile phones and the Internet. Data transfer through this tunnel is encrypted and prevents Internet theft or hackers from stealing or accessing information. Connecting to the Internet exposes one to all kinds of security threats and vulnerability. A VPN is an extra layer оf security that ensures protection on the web. The VPN provides different сhоісе of servers аll over the world. Premium VPN providers offer servers in the US, EU, and Asia.
VPN Protocols
Through the use of security procedures and tunneling protocols, the VPN can secure and maintain privacy. Below are examples of VPN protocols:
The PPTP
PPTP is referred to as Point-to-Point Tunneling Protocol. Traffic is encrypted using 128 bits keys. PPTP is less secured compared to other VPN protocols. However, this protocol meets the basic demands or requirements of many users.
The L2TP
L2TP, also called Layer 2 Tunneling Protocol, is more secure than the Point-to-Point Tunneling Protocol. L2TP is combined with IPSec protocol, which utilizes a better-protected encryption algorithm. This protocol is much secured because it combines 168-bit keys and 3DES encryption algorithm.
The SSTP
SSTP offers more security compared to other protocols; it is the most secured protocol. The Secure Socket Tunneling Protocol (SSTP) is an SSL VPN protocol. It utilizes 2048 bit keys and also authentication certificates.
The SST can operate in network environments that inhibit or blocks VPN protocol. This function of SSTP makes it stand out when compared to other VPN protocols. Some countries or companies prohibits using VPN connection. In situations like is, SSTP is recommended.
The SSL
This is known as Secure Sockets Layer and is mostly used. This type of VPN protocol can be used through a standard web browser on the computer. It does not require any installation of specialized client software on the computer which is common in IPSec.
Benefits Using the VPN
- Provides security and prevention of data theft
- Provides uncensored Internet access
- Provides unblocking ability for sites
- It protects browsing history
- Supports popular p2p protocol like Bit Torrent
- Provide privacy by hiding internet activity from ISP and government
- Allow you to evade censorship (by school, work, your ISP, or government)
- Provides access to geographical restrictions
- Protect you against hackers when using a public Wi-Fi hotspot

Large corporations, small business, and individuals make use of virtual private network which provides security and permits access to network resources (databases, shared files, devices). It encrypts connection, secures traffic between VPN servers and users and also prevents interceptions or tracking. The VPN is recommended for individuals seeking privacy and secured connections.
